When you notify us of a planned service that is subject to the protocol, we’ll conduct a clinical review to determine if the service is medically necessary and covered, and will let you know our decision.

If the member's benefit plan does not require a clinical review and the service does not meet clinical guidelines, or if additional information is needed, we’ll let you know if you need to have a physician-to-physician discussion.
